Foreword: In order to solve the problem of diversification and complexity of analog quantity collection in engineering vehicles, a configurable analog quantity acquisition module is designed. This module is used in a universal vehicle controller based on Freescale’s 32-bit microprocessor MPC5646B. The hardware design scheme

Background introduction In control systems with more complex functions, RS232 serial port communication plays a crucial role in facilitating data exchange. The host computer is typically an industrial computer, while the slave computer is a single-chip microcomputer. In these applications, the single-chip computer interfaces directly

Abstract: In order to solve the problem of line selection and location of small current ground faults in the distribution network, this paper analyzes the adaptive filtering properties of the EMD algorithm. The IMF decomposed by EMD of the small current ground fault current displays

Introduction to the paper: As people’s requirements for power quality are getting higher and higher, the power supply reliability of distribution networks has received great attention. The distribution terminal DTU of the switching station is an important part of the distribution network system. The remote

The distribution automation terminal is the execution unit of the distribution automation system and an important part of the distribution automation system. It mainly monitors and controls the switching equipment in the distribution system and has functions such as fault location and isolation, system protection,

In the Internet of Things, short-distance wireless communication technology is constantly developing and innovating. Short-distance wireless communication technology is mainly divided into two categories. One is LPWAN (low-power Wide-Area Network, low-power wide area network), which is often called Wide area network communications technology. The other

The proposal of distribution automation has led to rapid development of the power market. It integrates modern communication technology, computer technology, automatic control technology and other technologies to realize the monitoring, management and control of the distribution system. The distribution automation system uses distribution automation
